BIOS Bias

A bootstrap script


Way down deep in the innards of a PC there lives a tiny control freak named the Basic Input/Output System.


And that's just the beginning.

"The BIOS software has a number of different roles, but its most important role is to load the operating system. When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere.

It cannot get it from the operating system because the operating system is located on a hard disk, and the microprocessor cannot get to it without some instructions that tell it how."


Here are a couple of links for more information:

RAM Restricted

32 bit Limit


OK, you have Vista Ultimate, you have a fast machine, but never satisfied you decide to cram it with RAM.

You sweat through installing the chips in these stunted cases manufactures use today.

You switch on the box and . . . What? Only 3451 MB is showing.

A 32 bit machine can only use about 3500 megs. Shades of the old 640K barrier.

Here's an explanation:
Where's my 4 Gigabytes of RAM?

Also:
The system memory that is reported is less than you expect if 4 GB of RAM is installed
